Hrustic makes Australia squad for football World Cup qualifier

The 20-year-old Melbourne-born Groningen winger could make his debut in a squad that contains 24 overseas-based players and just six from the domestic A-League for the match at Adelaide Oval on June 8.

Postecoglou selected six uncapped players and a set of brothers in Ryan and Dylan McGowan among his core group of European-based stalwarts -- Mile Jedinak, Tom Rogic, Aaron Mooy, Massimo Luongo and Mathew Leckie.

Former Everton star Tim Cahill, 37, and chasing a 97th cap, was also included.

The squad, which will be trimmed to 23 players on May 31, will also play a friendly with Brazil in Melbourne on June 13 before competing in the Confederations Cup in Russia, where the Socceroos face Germany, Cameroon and Chile in the group stage.

"I'm happy with the 30-man squad we have been able to name for the upcoming June international window but initially our energy and focus will be solely on the World Cup qualifier against Saudi Arabia in Adelaide," Postecoglou said.

"It is the most important game we will play over the June period.

"The group is tight at the moment and Saudi Arabia will be a tough opponent, but we have always been strong on home soil and I see no reason why that won't continue in front of our fans at Adelaide Oval."

Japan and Saudi Arabia head Asia Group B on 16 points among the two automatic qualifying spots, three points ahead of Australia with three games remaining.
